Abstract

Mobile and portable technologies frequently adopt heterogeneous multimedia networks. In this context it was designed scalable video encoders where a scalable video stream is transmitted containing a base layer (responsible by the minimum video requirements) and additional enhancement layers (each one improving the video characteristics). Recently MPEG and ITU-T groups published the scalable HEVC standard specification. However, the whole implementation of this encoder demands large computational resources and memory size. The current work presents a detailed analysis of this technology and its internal modules, indicating a simplified configuration that reach a tradeoff among low latency time and encoding quality. Comparison results indicate it as a fast and low complexity solution with small video quality loss.
